Specification of Letters Patent.

Patented Oct. 2, 1906.

Application led December '7, 1905. Serial No. 290,692.

of which the following is a specification.

This invention relates to improvements* in lmeans forA skimming cream from milk contained in bottles such as are ordinarily used for the delivery of milk; and it consists in certain peculiarities of the construction, novel arrangement, and operation of the various arts thereof, as will be j hereinafter more lly set forth and specifically claimed.

The principal object of the invention is to provide a' handy, simple, inex ensive, and efficient skimming device whic while it is more especially intended to be used for skimming cream from milk contained in ordinary plicable for skimvide a device of the above-named character which may be manipulated by the use of one hand, thus ermittmg the other hand to be employed w en desired to hold the vessel in lWhlch the cream is to be deposited.

Other objects and advantages ofthe invenf tion will be disclosed in the subjoined description and explanation;

In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe it, referring to the accompanying drawings, in whichf Figure 1 is a central vertical sectional view of a portion of a milk-bottle, showing a skimmer embodying my invention in lace therein. Fig. 2 is a top plan view'o the Fig., 3' 1s a plan sectional view thereof. Fig. 4 is a detached face view of the skimmer-valve, and Fig. 5 is a detached perspective view of the holderfor the skimmer-tube and operating or valve rod.

Like numerals of reference refer to correspondin views of t e drawings.

The reference numeral 10 designates a milk-bottle which, as usual, is surrounded at its mouth with an outwardly-projecting rim or bead 1 1 and has in its upper portion an annular recess 12 to receive a stopper which is in the form of a disk and may be made of cardboard or other suitable material. The skimmer consists of a tube or cylinder 14,

parts throughout the different which may be made of any suitable size, form, and material, but preferably of sheet metal and of a size to permit it to be easily inserted in the neck of the bottle or vessel in which the milk to be skimmed is contained. The lower end of the tube or. cylinder 14 is open, but is rovided with a horizontallv inturnedannu ar flan e 15, as is clearly s.. 'wn in Figs. 1 to 3, inc usive, of they draaings. The upper end of 'the tube 14 is provided with inturned lips 16, which are located diametrically opposite each other, and each of said lips is provided with an open slot 17 for the reception and operation of the vertical mem ers of the skimmer-holder, which consists, y preference, of a single piece of wire bent to form two loops 18, whichv diverge from one another, and two arallelmembers 19, the lower end of each o which is formed with an outwardly-extending projection 20 to engage indentations or depressions 21 on v the inner surface of the tube and about midway between its upper and lower ends. In order to prevent that portion of the metal in which the indentations 21- are formed roxjecting outwardly from the circle described by the tube or cylinder, an1iI1ward1y-extend ing depression 22 is formed around each of sald indentations, as is clearly shown in Fig. 3 of the drawings. holder is formed about midway between the loops 18 withfa coil or loop 23, in which is located the valve or operatlng rod 24, the uper end of which is provided with a ring 25 or the reception of one of the fingers of the operator. The rod 24 is provided at a suitf able point below the coil or loo 23 with a collar or rejection 26, to whic is secured one end o a spring 27, which is coiled around the rod and has its other end attached to or resting against the lower portion of said loop. Secured tothe lower end of the rod 24 is a valve 28, "used to close the opening in the lower end of the tube, and is provided with a series of radial projections 29 to rest on the flange 15 in the bottom of the tube and to act as uides for the valve.

s is clearly shown in Fig. 4, vthe projections 29 are spaced apart, so that when withdrawing the older and valve from the tube for the purpose of cleaning the parts the valve may be turned so as to stride the lips 16 on the upper portion of the tube or cylinder. To place the holder in position in the tube, the members 19 are pressed toward each other, when they, as well as the valve and its .85 The wire comprising the IOO 30 the vessel and the cream deposited in anrod, may be inserted in the tube until the projections on the lower ends ofthe members reach the depressions 21, when the pressure may be removed from said members,

normally actuate the rod 24, so as to press the valve 28 against the flange 15.0f the tube,

thus closing the opening in its lower end; but when it desired to skim the milk or remove the cream therefrom the valve may be raised to about the position shown by dotted lines in 1, thus permitting the cream to enter the tube and pass .through the spaces between the rojections 29 on the valve and the wall of t .e tube, after which the valve will be closed by means of the spring 27 on the operating-rod. By forming the holder with the loops 18 it is a parent that the first and third fingers of thelhand of the o erator may be inserted in said loops, whilet e second or middle inger'may be inserted in the ring on the operating-rod for raising the valve. From the above description it is ap-v parent that the tube when the holder is 1n engagement therewith may be removed from other receptacle and also that the parts may "be easily separated, so that the devlce may be thoroughly cleansed. v

Having thus fully described my invention, 3 5 lwhat I claim as new, and desire to secure by v Letters Patent, is-

1. The combination with a tube having atits lower end an inturned annular flange and provided internally between its ends with indentations, of aholder having yielding prongs and a air of loops, the said prongs extending into t e tube and having projections to engage said indentations, a spring actuated va ve-rod mounted on the holder between its loops, and a valve on the lower p'ortion of said rod to rest on the flange of the tube and to close the opening therein, substantially as j described. o

2. The combination with a tube having at its lower end an inturned annular flange and provided internally between its endsy with diametrically disposed indentations, of a holder consisting of two parallel members having spaced-apart yielding loops and pro= vided between said loops with an intermediate loop, the said members extending into the tube and having projections to engage the indentations therein, a spring-actuated valve-rod movably located in the intermediate loop oi the hol-der, and a valve on the lower portion of said rod to rest'on the flange of the tube and .close the opening therein,

substantially as described. l
